Similarity & Transformation
You can put a sub headline here.
Similar- if one image can be obtained from another by a sequence of transformation & dilations
To find if the figures are similar you have to translate triangle ABC down 2 & 1 left so c can match up to E. Then you have to write the ratios of the lengths sides
CB/ED= 2/2 or 1/1, BA/DE= 4/2 or 2/1, AC/FE= 4/2 or 2/1
since the ratios don't math they aren't similar. All sides have to equal so they can be similar
